Grey Dune
Grey dunes are fixed, stable sand dunes located 50–100 m from the edge of the ocean. Grey dunes occur on the landward side of bare white dunes. They are so named due to the presence of grasses and lichens such as the Cladonia species. This creates the characteristic grey colour.

Famous quotes containing the word grey:
“I’ll walk where my own nature would be leading:
It vexes me to choose another guide:
Where the grey flocks in ferny glens are feeding;
Where the wild wind blows on the mountain-side.”
—Emily Brontë (1818–1848)
